API Terms of Service

These Terms of Service were last updated on February 10, 2012

The Fitbit API (the "API") is provided as an asset to community members and partners to facilitate innovation in health, wellness and tracking applications. It is designed to interact with and enhance the Fitbit Tracker and the Fitbit user platform.

While we try to provide the most open and flexible access we can, we aim to support a balance between developers' needs, users' privacy, and the integrity of Fitbit's product and business vision. To that end, we anticipate that the Fitbit Platform, our API and these Terms of Service will evolve over time. We will update these Terms of Service as needed or required and will always post such updates here.

If there is a use case you would like to see covered that is not currently supported by the API or these Terms of Service, please contact us at api@fitbit.com to discuss your needs. Additionally, please participate in the Fitbit API developer group, which can be found here.

  5. Respect Users and their Privacy
    • Be clear to Users about what User Data will be retrieved from or submitted to Fitbit when they use your Application.
